This is the classic beauty in sound, admired by audiophiles for almost 60 years and will still be our top choice in the next 60 years. Particularly, the early '60s Siemens tone is considered the \"reference sound\" for serious classical listeners who need to upgrade the sound quality at phono stage. \u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-family: Arial; font-size: large;\"\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"color: #2a633a; font-family: Arial; font-size: large;\"\u003e\u003cb\u003eSound Characteristics \u003c\/b\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-family: Arial; font-size: large;\"\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-family: Arial; font-size: large;\"\u003eThe airy and transparent sound produced by these vintage Siemens tubes has been unrivaled even to this day. The magically extended yet never tizzy highs, coupled with the slightly focused upper mid-range, deliver a clear presentation of the entire frequency spectrum, completed by the precise and deep controlled bass. And the most defining sound characteristic of Siemens ECC82 tubes is their ability to retrieve the deepest levels of detail in sound, and these hidden sonic layers can go a long way to revealing the subtle ambient clues that help complete building a truly 3D holographic presentation. While as quiet and analytical as the best Telefunken ECC82 tubes, Siemens tubes produce a warmer, smoother and more musical sound. \u003c\/span\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-family: Arial;
